Treacher Collins syndrome is a genetic condition that leads to problems with the structure of the face. Most cases are not passed down through families.
Mandibulofacial dysostosis; Treacher Collins-Franceschetti syndrome
Changes to one of three genes, TCOF1, POLR1C, or POLR1D, can lead to Treacher Collins syndrome. The condition can be passed down through families (inherited). However, most of the time, there is not another affected family member.
This condition may vary in severity from generation to generation and from person to person.
Symptoms may include:
Hearing loss is treated to ensure better performance in school.
Being followed by a plastic surgeon is very important, because children with this condition may need a series of operations to correct birth defects. Plastic surgery can correct the receding chin and other changes in face structure.

Complications may include:
This condition is most often seen at birth.
Genetic counseling can help families understand the condition and how to care for the person.
Genetic counseling is recommended if you have a family history of this syndrome and wish to become pregnant.
